I've got 8 young cory fry in a little breeder at the moment. They are about 1 week old and don't seem very active. They seem to rest in the same place for hours without doing anything. Is this normal fry behavior?
perfectly normal yes, they tend to hide in any dark corners of the nets away from the light. Ideally you might have something to put in there to give them a bit of cover, plant matter of some sort.
They're much more active a few days on. Seems like they hatch quite active with their yoke sacs then once they are used up they have a day or so of being more inactive before perking up again.
In other news the next batch of eggs is about to hatch. I can see them wriggling inside.
